Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00189 | $0.01997 |
| Opus 5 | $0.00095 | $0.00999 |
| Sonnet 5 | $0.00038 | $0.00399 |
| Haiku 4.5 | $0.00019 | $0.00200 |
Grade A, and why
creating-video scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Creating Video
Claude cannot render video itself, but it can direct a generator. This skill drives a multi-clip pipeline — script → per-scene generation → review → assembly — with Claude as the editing agent overseeing continuity and cut.
Requires ffmpeg/ffprobe and Cloudflare AI Gateway creds (/mnt/project/proxy.env).
Default model: Gemini Omni Flash (gemini-omni-flash-preview, Interactions
API) — Google's own guidance as of 2026-07. It beats Veo on character
consistency, reference-image control, text rendering, and conversational
editing, and generates faster (~30–90 s/clip vs 1–3 min). Fall back to Veo
3.1 (scripts/veo_generate.py, kept intact) only for scene extension,
first+last-frame interpolation, or legacy pipelines — Omni supports neither.
The five stages
- Shot list — break the story into beats, up to 10 s each, one prompt per shot.
- Generate —
scripts/omni_generate.py, run detached. - Review —
parsing-videoon each clip and on the assembled cut. - Assemble —
scripts/assemble.py, run detached. - Iterate — re-review, then edit failing scenes conversationally (cheaper and more stable than regenerating from scratch).
Stage 2 — Generation (Omni via Cloudflare AI Gateway)
Auth is CF AI Gateway BYOK: proxy.env supplies CF_ACCOUNT_ID, CF_GATEWAY_ID,
CF_API_TOKEN; the Google key lives inside the gateway. Both the interactions
call and the files/{id}:download retrieval route through it (verified 2026-07-20).
Run detached. The Interactions API is synchronous — the HTTP call holds
open for the whole generation (~30–90 s/clip). bash_tool caps at ~50 s. Launch
and adaptive-wait on the DONE sentinel:
# prompts.json = {"1": "...", "2": {"text": "...", "images": ["ref0.png"]}, ...}
set -a; . /mnt/project/proxy.env; set +a
(setsid python3 scripts/omni_generate.py prompts.json --out omni/ \
--negative "on-screen watermark" &)
# then, in a separate call:
timeout 45 sh -c 'while [ ! -f omni/DONE ]; do sleep 3; done'; cat omni/generate.log
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 12d ago First seen · 141 lines · 189 tokens per session scan A 1625035205a9
creating-video is a skill published in the GitHub repository oaustegard/claude-skills (148 stars, last pushed yesterday), licensed MIT. It adds 189 tokens to every session and 1,997 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
